COMBINE LIFTING AN TRACK ALINING JACK.

SPECIFICATION forming part Of Letters Patent No. 696,613, dated April 1, 1902..

Application filed July 29,1901. Serial No. 70.016- (No model.)

To aZZ whom, it may con-007%.-

Be it known that I, PETER JOHAN MANSON VVASLYNG, a subject of the King of Great Britain, residing at Savanne, county and district of Algoma, Province of Ontario, Canada, have invented certain new and useful Improvements in a Combined Lifting and Track-Alining Jack; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a combined lifting and track-alining jack; and the object that I have in view is the provision of a simple and cheap construction adapted to work in either a vertical. or a horizontal position for the purpose of lifting a rail or of pressing horizontally thereon, respectively, while in such positions, the pressure-claw of the jack being adapted to engage with the head or the foot of the rail, as may be desired.

With these ends in view the invention consists in the novel combination, construction, and arrangement of parts which will behereinafter fully described and claimed.

In the drawings hereto annexed, forming a part of this specification, Figure 1 is a side elevation of my combined lifting and alining jack especially adapted for use on railway-tracks, the jack being shown in its upright position and adapted to the work of raising a railway-track. Fig. 2 is a longitudinal sectional elevation through the jack, showing the same in its horizontal position and adapted to the work of exerting pressure in a horizontal plane against a rail of a track. Fig. 3 is a horizontal sectional plan view through the framework of the jack. Figs. l, 5, and 6 are fragmentary detail views of the parts of the jack, which will be hereinafter more fully referred to.

The same numerals of reference denote like parts in all the figures of the drawings.

The framework of the jack comprises a base 5 and a standard 6, the latter being provided in one side with a longitudinal slot 7. The base is furnished with a slot 8, that com municates with the longitudinal slot 7 in the standard and is adapted to permit of the free passage of a lifting-toe 9, which is provided at one end of the slidable bar 10. The standard forms a guideway that is arranged to snugly receive the slidable bar,the latter being limited to endwise movement in the standard. The lifting-toe 9 of the slidable bar extends through the slot 7, and said lifting-toe is adapted to pass freely through a slot 8 of the base 5 when the bar 10 is drawn back into the standard.

The slidable bar is provided at one edge with a series of teeth 11 and at one end with a male-threaded stud 12. A claw 13 is provided with an angular end 14, in which is produced a female threaded opening 15, whereby the claw may be screwed detachably to the threaded stud of the slidable bar. The claw lies at an angle to thelength 0f the bar, and it extends outwardly therefrom, and the free end of this claw terminates in a reversely-inclined nose 16, whereby the claw and its nose are adapted to have proper engagement with the head or ball of a rail, as indicated by Fig. 2.

17 designates a lever-socket, which is cast in a single piece of metal and is adapted to receive a suitable handle-bar in a manner similar to ordinary lifting-jacks and. as will be understood by those skilled in the art. This lever-socket is connected by a bolt 18 to the standard 6, and the inner end of this socket is furnished with a plate 19, the same extending beyond the end of the socket proper and provided with a stud or boss 20. (See Fig. 4.)

21 designates the feed-pawl, which is made as an integral part of the disk or plate 22,

having an eye 23, and this pawl is furthermore provided with a finger-piece 24, that is integral with the plate or disk 22 and is arranged to extend outwardly toward the leversocket in a manner to expose the finger-piece always to convenient access. (See Fig. 2.) The feed-pawl is fitted on the stud 2 0 of the lever-socket, which stud snugly fills the eye 23 of the pawl plate or disk 22, and the pawl is thus arranged on the lever-socketiu a manner to engage with the teeth 11 of the slid able bar.

25 designates a check-pawl which is pivoted at 26 to the standard 6 in a position to engage with the teeth 11 of the slidable bar.

A spring 27 acts against the check-pawl in a manner to normally hold it in engagement with the toothed bar. a

From the foregoing description, taken in connection with the drawings, it will be understood that the jack may be arranged in the upright position shown by Fig. 1, so as to rest upon the base-plate 5. The lifting-toe 9 of the slidable bar is adapted to be placed beneath the base of a rail, and the operator can then work the lever in a well-known manner to make the pawl 21 impart an endwise movement to the bar 10, thereby elevating the too 9, and with it the rail. pawl 25 may easily be disengaged from the bar 10, and the operator can also press upon the finger-piece 24 in order to retract the feedpawl from like engagement with the bar, thus enabling the bar to be drawn downwardly into the standard. As shown by Fig. 2, the jack may be arranged in a horizontal position, so that the base-plate 5 will rest against a suitable obstruction, such as 28. This allows the claw 13 to be brought into engagementwith the head of the rail, or, if desired, the jack may be dropped to a still lower position, so as to bring the nose and the claw into engagement with the foot of the rail. The lever and the feed-pawl may be operated in order to impart endwise movement to the The check tial features are retained and the spirit of the invention is embodied. Hence I do not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom.

' Having thus described my invention, what I claim as new is- A jack of the class described comprising a slotted standard, a slidable bar provided with a claw and with a lifting-toe, a lever-socket fulcrumed on the standard and provided with a plate having a stud or boss, and a feedpawl loosely mounted on the stud or boss and having an offstanding finger which is exposed at all times outside of the limits of the leversocket, substantially as described.

In Witness whereof I have hereunto set my hand in the presence of two witnesses.
